The report was apparently leaked to the New York Daily News. According to the News, the report found that Scheindlin decided against law enforcement in 60 percent of her written opinions on "search-and-seizure" over the course of her nearly two decades on the bench. The study allegedly also says that rate is the highest among 16 current and former Manhattan federal judges that the report included since 1990.

The mayor's office reportedly declined to comment to the News, but Scheindlin told the News that the study is "completely misleading" as it doesn't include any rulings from the bench.

While the majority of her written opinions may involve dismissing evidence, she told the News that in "nearly all" of her bench rulings on seized evidence, she has denied motions to suppress.

CCR released a statement calling the report "nothing short of outrageous."

"Having already attacked the Center for Constitutional Rights, communities mobilizing to end violent and discriminatory policing, and the press, the attack on a respected judge scrapes the bottom of the litigation barrel," the statement read.

CCR recommended that the city instead focus on "studies to remedy the persistent constitutional violations in its police department."

NYPD spokesman Paul Browne did not immediately respond to a request for comment as to whether the NYPD was responsible for the leak, as CCR's statement implied.
